What is the relationship between mass of an object and its acceleration?

What is the relationship between mass of an object and its acceleration?

To find a relationship between the mass of an object and its acceleration, I will have to conduct a practical experiment, using a method and equipment that will enable me to obtain accurate results. I can also use formulae to show a relationship, but the practical will prove any relationship.

This experiment is aimed at finding the relationship between the mass of an object and its acceleration. To do this I will set up a cart, that will have a varying mass, and I will measure the acceleration of the cart, with a constant force pulling it. I will be able to measure the acceleration using light gates and a computer.


Using formulae, I can prove that there is a relationship between the mass and acceleration of an object.  The Formula, F = M x A can help me show this relationship:

Force = Mass x Acceleration.

The force pulling the cart will remain constant, at 5N (Newtons). As the force remains constant, at 5N, when either the mass or acceleration of the cart increases, the other factor must decrease to keep the force constant. To show this I can enter the numbers into the equation, shown below.

As the results from the trial run were not accurate enough to help us answer the question, we modified the method to gain this accuracy. During the trial run, we approximated the mass of the cart to 1000g. The exact mass of the cart during the final experiment is 850g; this is including the timing card and the plastecine used to hold it in place. The exact mass will help us gain a greater accuracy.

  1. To start with, we measured the mass of the cart: This was 850g.
  2. We attached a timing card to the cart. Modification: originally, we used two light gates, and a solid piece of card; this method was less accurate, and required two light gates. Then we used a piece of card with a slot cut from it, and using one light gate, we were able to measure the acceleration. As we had made the timing card ourselves it was less accurate. In the final experiment, we used a purpose built timing card, made from plastic, which enabled us to achieve a much greater degree of accuracy.
  3. We attached 500g (5N)

Overall the results we gained were very similar to what we had expected, as the shape of the graph we had predicted was achieved, although the results were not as accurate as we had expected, due to the reasons explained above. To get more accurate results I could have added more mass on at a time so that the results represented a greater reading of mass. This should help me to achieve better results. The results that we got were enough to answer the question, and looked like those from the prediction so we did not have to conduct the experiment more than three times. I think my prediction was correct in that the relationship between the mass of an object is inversely proportional to its acceleration.

  1. Investigate how the weight of an object affects the force required to overcome friction.

    I also predicted that the static and dynamic friction would be directly proportional to the weight of the object pressing down onto the surface. This has also been proven true as nearly all of my points, except for a few that are probably anomalous results anyway and which I

    would also increase. The graph shows the average results for 1/mass against acceleration. The main point that I have focused on so far is that when this graph is plotted, because of its direct relation to the formula F = ma, the graph shows the following a = F (1 / m).

    results can tell us something of the relationship between force acceleration and Mass, there is definitely a positive relationship between these three factors. This relationship may in fact be a proportional relationship with other factors involved since we have seen that removing some of the external factors has made the relationship closer to a proportional one.

    For the secondary experiment, I chose to be working with weight going up by 200g each time. Five or six is always a sensible number of results to obtain, so I will go up to about 1kg. Again, a minimum of three readings should be taken on each weight for a mean average to be taken.

    Another precaution is making sure that the weights on the trolley are securely placed, or fastened, to the trolley, so that they do not come off from the trolley and cause injury. Equipment: I will need a special ramp with elastic at one end, books to put under the ramp

    As well as this I must consider how accurate I want my results to be. As seen above I think that giving my results to 3 decimal places would be appropriate as this allows good continuity and does not suffer from premature approximation.

    Gravitational potential energy (g.p.e.) is mgh, and kinetic energy (k.e.) is 1/2mv2. If we consider the mass of the trolley to be m1, and the dropping mass to be m2, this gives us g.p.e. as m2gh, as only the dropping weight has g.p.e.
